Product Description

These barrels come from the same machines and the same people who make the military MK12 barrels for the Special Operations community. These barrels are the result of tens of thousands of dollars in development done by the U.S. government to give our Special Operations guys the best weapon system they can have. We have spoken with many operators who have used these barrels and carried them in combat and have found unanimous satisfaction with their reliability and accuracy. No break-in is required by the end user.
